Application filed August 5, 1913. Serial No. 783,022.

To all whom it may concern Be it known that I, CHARLES R. LAW, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Car J ournal-Boxes, of which the following is a specification.

This invention relates to new and useful improvements in car journal boxes, and more particularly to the box in which the journal of the axle of the ordinary railway car has a hearing.

The object of the invention is to provide a box of the character described whose outer end is completely inclosed and whose entrant opening to the interior of the box is on the side thereof. In the ordinary axle box the entrant opening to the interior thereof is at the outer end and is protected by'a door or covering but when used on cars for carrying logs or other heavy articles which are loaded on to the cars ordinarily by means of lifting cranes, the protecting doors of the boxes are often broken from the boxes by reason of the fact that the heavy article in being swung into position upon the cars strikes against the outer ends of said boxes, thereby breaking and dislocating said doors and leaving the interior of the boxes unprotected against the entrance of sand and other foreign matter. It is the chief object of this invention to obviate this defect.

Another object of the invention is to provide a box of the character described so constructed that the impact of said heavy articles against the outer end of the box, in the process of loading, will be received by the outer end of the axle, thus preventing the inner'side of the box from impacting against the car wheel and injuring or breaking said inner side of the box.

Another object of the invention is to provide a box of the character described so constructed that easy access may be had to the interior thereof for the purpose of removing and replacing the journal bearing and for the further purpose of applying lubricating means to the journal.

With the above and other objects in view, the invention has particular relation to certain novel features of construction and arrangement of parts, an example of which is given in this specification, and illustrated in the-accompanying drawings, wherein- Figure 1 shows a front view of the trucks of a car, the axle of which is journaled in my improved form of box. Fig. 2 is an end vlew of the box. Fig. 3 is a sectional end view thereof. Fig. 4 is a side elevation thereof. Fig. 5 is a vertical sectional view thereof. Fig. 6 is a plan view thereof. Fig. 7 is a plan view of the door protecting the side opening of the box, and Fig. 8 is an end view thereof.

Referring now more particularly to the drawings, wherein like numerals of reference-designate similar parts in each of the figures, the numeral 1 refers to the axle to which the wheels 2 are fixed. The axle 1 extends each way beyond the wheels and said projecting ends are formed into journals, as -3. The journal box 4 is substantially square in cross section and in general contour is of the usual form. The box is cast hollow and with its inner end open and the journal 3 of the axle extends through said open end into the interior of the box. The outer end of the box is entirely closed and the outer end of the j ournal3 is spaced only a short distance from the outer end of the box so that any impact received by the outer end ofthe box will be sustained by the axle journal and the inner end of the box thus protected against impact against the car wheel.

Thenumeral 5 refers to the bearing for the journal 3. This bearing is usually formed of brass and in cross section is archlike inform, the under side thereof being concaved so as to fit upon the journal 3, as shown in Fig. 3.

One side of the box 4 has an oblong opening for the purpose of permitting access to the interior of the box. This opening is protected by a removable covering 7 which is an oblong, thin, metallic plate. This plate is held in position by means of a strong flat spring 8 which is pivoted at its center to the center of the covering 7 and whose ends engage"inarc-uate grooves 9, 9 at opposite ends of the box and when so engaged hold said covering in position. The spring 8 may be swung around on its pivotal support so as to disengage its ends from said grooves when it is desired to remove said covering. Any other method, however, of securing the covering in position may be employed. The boxes of the different trucks are fixed in position relative to each other by means of iron bars or straps, 9, 9', above and below and lugs 10, 10 project out from the bottom and top of'the box 4: above and below the V for each box instead of two short ones, said 7 bolt. extending through both straps 9, 9, so

as to clamp them above and below the box, but I have provided the two short bolts and the lugs 10, 10 sothat there will be no obstruction to prevent or interfere with the free removal of the door 7, or its replace- 'me'nt in position. It is further to be observed that. the oblong opening at the side of the box 4, and which is closed by the door 7 is at the upper side of the box, as is more clearly indicated in Fig. 3, so that the bottomrof the box will form a'lubricant receptacle and'there'will be no liability of the lubricant escaping through the sideopening of the box. Integral with the inner face of this covering and extending. inwardly therefrom is an oblong lug 10 and projecting inwardly from the opposite side of the box 4 and integral therewith is a similar lug 11, the said lugs '10 and 11 embracing the bearing 5 on each side ,andholding the same in position above the journal 3. e

' The numeral 12 refers to a dust guard having a central orifice through which the journal 3 extends. This guard is a thin, fiat body composed. of woody or fibrous material and is provided to close the inner end of the box and'protect the interior thereof from dust and foreign matter, as well as to prevent the escape'of the lubricant from the interior of the box( This guard fits down into a groove '13 which extends aroundithe inner wall of the inner end of the box and has free vertical play in said groove.

' When it becomes necessary to remove or replace any of the internal parts of the box or to lubricate the same, the covering 7 may be removed as hereinbefore described; The

7 box 4 is then jacked up by means of the ordinary lifting jack, relative to the axle, the internal chamber of the box being sufficiently large to permit this relative move ment of said'box and axle. Access-is thus gained to the interior of the box and the bearing 5 and wedge 6 maybe adjusted, removed, or replaced as circumstances may require, and the box otherwiseadjusted or lubricatedas may be found necessary. As the box 4 is moved up or down relative to the axle, the guard 12 slides up and down in the groove 13 but at all times blocks the opening through the inner end of the box into the interior thereof and prevents the entrance of sand and foreign matter into the interior of the box and also prevents the escape of the lubricant-retaining waste with which the internal chamber of the box is ordinarily filled.

What I claim is:' V

In a device of the character described, the combination with a car axle of a box having an internal chamber, the inner end of said box being completely open, said end being enlarged and having an internal groove therein, a dust guard carried by said box and located in said groove through which the axle journal passes for closing said open end, said dust guard forming an *inclosed reservoir with the bottom of said box and the opposite end of said box being entirely closed and being an integral part thereof, one side of said box being provided with an oblong entrant opening arranged therealong near the top of the box, a closure for said opening, a flat spring bar for resiliently securing said closure in position over said opening, a detachable bearing member within the box and forming a bear ing for the axle journal, one inwardly projecting lug carried by the door and an inwardly projecting lug fixed 'to the opposite side of the box, said lugs resting againstthe opposite sides of the bearing member and holding it in position, said entrant opening being provided through which said bearing member 'may be removed and replaced, lugs projecting from the side of said box above and below said entrant opening, said lug being provided to receive the securing means whereby said box is fixed in position.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
